Head-swinging dual-compound braking device

Abstract

The invention discloses a head-swinging dual-compound braking device. The head-swinging dual-compound braking device comprises a rotating mechanism, a brake mechanism, a motor rotor and a swing head main body, and is characterized in that the brake mechanism comprises a brake device, a driving device and a brake auxiliary assembly; the brake device comprises a first composite brake disc and a second composite brake disc; the driving device comprises an oil cylinder, a first piston cylinder arranged above the first composite brake disc and a second piston cylinder arranged below the second composite brake disc; the brake auxiliary assembly comprises a spacer bush; and an outer side flange part of the spacer bush is located between the first composite brake disc and the second composite brake disc. According to the head-swinging dual-compound braking device,The piston cylinders are driven by the oil cylinder to extrude the two composite brake discs; air in a cavity between the two composite brake discs is extruded; counter-acting force extrudes the inner sides of the composite brake discs; the composite brake discs are subjected to hydraulic and air pressure effects at the same time; stress on the composite brake discs can be more uniform; in addition, loss in the pressure transmission process can be effectively avoided; braking is more stable; and the braking effect is higher.

Description

technical field [0001] The invention relates to the technical field of oscillating head braking, and more specifically relates to a double compound braking device for oscillating head. Background technique [0002] At present, most of the swing head braking devices in the prior art are single-direction braking, the braking effect is poor, and the force is uneven, the stability is not high, and the braking energy supply mode is mostly single-mode energy supply, which cannot Meet the energy supply requirements under different working conditions. At the same time, the existing braking mechanism mainly uses pneumatic energy supply, which is supplied by compressed air. Due to the compressibility of gas, it is difficult to ensure air tightness, resulting in poor transmission accuracy and low supply capacity, and the pneumatic structure The large volume is not conducive to the flexible rotation of the swing head. [0003] Therefore, how to provide an oscillating head double compo...
